Abstract

A lamp for a vehicle may include a hologram reproducing apparatus reproducing a written image to an outside when light is input, a light source provided to one end side of the hologram reproducing apparatus, and a reflecting apparatus provided to another end side of the hologram reproducing apparatus and reflecting light of the light source to the hologram reproducing apparatus at a same incident angle as an incident angle when an image is written on the hologram reproducing apparatus.

First claim

What is claimed is:

1. A lamp for a vehicle comprising:
a hologram reproducing apparatus reproducing a written image to an outside when light is input;
a light source provided to one end side of the hologram reproducing apparatus; and
a reflecting apparatus provided to another end side of the hologram reproducing apparatus and reflecting light of the light source to the hologram reproducing apparatus at a same incident angle as an incident angle when an image is written on the hologram reproducing apparatus.

2. The lamp for the vehicle of claim 1 , wherein the reflecting apparatus forms an angle which is set with the hologram reproducing apparatus so that the light of the light source is incident into the hologram reproducing apparatus at a same angle as an incident angle of reference light when being written in the hologram reproducing apparatus.

3. The lamp for the vehicle of claim 1 , wherein the light source is provided to a position out of the hologram reproducing apparatus in one end direction of the hologram reproducing apparatus.

4. The lamp for the vehicle of claim 1 , further comprising:
a light source seating apparatus having the light source installed therein; and
a fixing protrusion formed to protrude from the light source seating apparatus and having a protruded end portion coupled to one end of the hologram reproducing apparatus.

5. The lamp for the vehicle of claim 4 , wherein the fixing protrusion protrudes to be higher than the light source so that the light generated from the light source is not directly irradiated to the hologram reproducing apparatus.

6. The lamp for the vehicle of claim 1 , wherein the reflecting apparatus has a reflecting surface formed in a plane.

7. The lamp for the vehicle of claim 6 , wherein a distance from the light source to the reflecting apparatus is set so that a moving distance of the light passing from the light source to the reflecting apparatus and incident into the hologram reproducing apparatus becomes equal to a moving distance of light irradiated from reference light when being written in the hologram reproducing apparatus.

8. The lamp for the vehicle of claim 1 , wherein the reflecting apparatus is formed so that a reflecting surface thereof has a set curvature.

9. The lamp for the vehicle of claim 8 , wherein the reflecting apparatus has the curvature which is formed so that all incident angles of the light reflected from the reflecting apparatus and incident into the hologram reproducing apparatus form a set angle.

10. The lamp for the vehicle of claim 1 , wherein the hologram reproducing apparatus has a front surface directing toward an outside of the vehicle, and the reflecting apparatus and the light source irradiate the light to a rear surface of the hologram reproducing apparatus.
